  • Detail

When the 7200gs series PG feedback control of motor soft starter is set in PG control mode (sn-13=11), plus fb-c speed feedback card, it can be used as v/f+pg closed-loop control

(I) standard wiring diagram

7200gs and fb-c card, power supply and peripheral equipment wiring. PG feedback control wiring is shown in figure

figure PG feedback control wiring diagram

(1) the speed feedback card (fb-c) is directly installed on the 3CN of the control substrate; The speed feedback card cannot be used at the same time with the following interface cards:

communication interface card: si-m card

analog monitoring card: ao-12 card

pulse monitoring card: pm-c card

digital output card: do-08 card

(2) fb-c card can only cooperate with the encoder of open collector and complementary interface type, and it needs to add a 12VDC, 0.3A output power supply to provide power for fb-c card and encoder

this parameter determines the number of pulses generated by the pulse generator (PG) every week. If PG is connected to the motor shaft through a gear box mechanism, a speed ratio will be generated. In this case, this proportion must be multiplied into the parameter. If it is set to 0, speed detection and control will not be performed. Pressure switch

for example, when PG parameter: 900p/r; Gear ratio: 1/8

then set cn-43 to 112.5 (900 × 1/8)。

(2) number of motor poles (cn-44)

set the number of motor poles. If the set value of cn-43 or cn-44 does not meet the following conditions, a setting error will occur and the message "PG parameter setting is incorrect ()" will be displayed. The set value is checked when the power is turned on or when switching from program mode to drive mode
